Which Air Purifier Is Best for Large Rooms?

If you want an air purifier that can handle a larger living room, open main area, or big bedroom without turning the buying process into homework, these three are the obvious shortlist: the LEVOIT Core 400S Air Purifier, the Coway Airmega AP-1512HH, and the Blueair Blue Pure 311i Max. All three are aimed at mainstream buyers who want better air cleaning in a bigger space, but they take slightly different approaches to convenience, controls, and day-to-day ownership.
